How to Connect a Soundbar to Your Samsung Smart TV

The fastest way: HDMI eARC or optical cable

Most Samsung smart TVs connect to a soundbar through one of two cables: HDMI eARC or a digital optical cable. HDMI eARC is faster to set up and handles more audio formats, so start there if your soundbar and TV both have an eARC port. If your soundbar is older or lacks eARC, the optical cable works just as well and costs less than $10.

The eARC port on Samsung TVs is usually labeled on the back panel — often HDMI 3 or HDMI 4, though this varies by model. Check your TV's manual or the back of the set itself. Once you plug in the cable, the TV recognizes the soundbar automatically in most cases. You may need to go into the TV's sound settings and select the soundbar as the default output, but Samsung makes this straightforward.

Optical cables require no power to the soundbar during connection, only when you want to use it. The cable plugs into the TV's optical audio out port (a small square opening, usually near the HDMI ports) and into the soundbar's optical in port. Again, set the soundbar as your audio output in the TV's settings, and you are done.

Key Takeaways

HDMI eARC is the preferred connection method because it sets up faster and supports more audio formats than optical cable.
If your soundbar lacks eARC, a digital optical cable works reliably and costs under $10.
After plugging in the cable, open your TV's sound settings and select the soundbar as the default audio output device.
Bluetooth pairing is an option for wireless connection, but it introduces latency and is best used only if wired connection is not possible.
If sound does not play through the soundbar after connection, check that the TV's internal speakers are disabled in the audio settings.

Setting up HDMI eARC step by step

Locate the eARC port on the back of your Samsung TV. On most models made in the last five years, this is HDMI 3 or HDMI 4. The port may be labeled "eARC" or "ARC" on the panel itself. Plug one end of an HDMI cable into this port and the other end into the eARC port on your soundbar. Use a cable rated for HDMI 2.1 or higher if you have one, though standard HDMI cables usually work.

Turn on both the TV and soundbar. Open the TV's settings menu by pressing the remote's home button, then navigate to Sound or Audio. Look for an option called "Sound Output" or "Speaker Settings." Select the soundbar from the list of available devices. The TV should recognize it within a few seconds.

Test the connection by playing audio or video content. If you hear sound from the soundbar, the setup is complete. If you still hear sound from the TV's internal speakers, return to the sound settings and disable the TV speakers or set them to off. Some Samsung models call this "TV Speaker" or "Internal Speaker" — turn it off so all audio routes through the soundbar.

Using a digital optical cable instead

If your soundbar does not have an eARC port, or if you prefer a simpler setup, use a digital optical cable. These cables are inexpensive and widely available. Locate the optical audio out port on your TV — it is a small square opening, usually grouped with the HDMI ports on the back panel. Insert the optical cable firmly into this port until you hear a click.

Plug the other end into the optical in port on your soundbar. The soundbar does not need to be powered on during this step, but turn it on before testing. Open your TV's sound settings, navigate to Sound Output, and select the soundbar. Play a video or music to confirm audio is coming through.

Optical cables do not carry video, only audio, so you will not see any picture-related changes. The trade-off is that optical does not support newer audio formats like Dolby Atmos, but it works reliably for standard stereo and 5.1 surround sound. If your soundbar supports Dolby Atmos and you want to use it, switch to HDMI eARC.

Connecting via Bluetooth if wired connection is not possible

Bluetooth is a wireless option, but it introduces a slight delay between the TV picture and the soundbar audio — usually noticeable during movies or shows. Use Bluetooth only if running a cable is not practical. Open your TV's Bluetooth settings, usually found under Sound or Connections. Set the TV to pairing mode.

Put your soundbar into pairing mode by pressing and holding its Bluetooth button (check the manual for the exact button and hold time). The TV should detect the soundbar within 10 to 15 seconds. Select it from the list of available devices. Once paired, the soundbar connects automatically whenever both devices are powered on and in range.

After pairing, go to the TV's sound settings and select the soundbar as the audio output. Test with video content to hear the delay for yourself — if it bothers you, switch to a wired connection. Bluetooth works best for music or podcasts where timing is less critical.

Troubleshooting when sound does not come through

If you plugged in the cable and set the soundbar as the output but hear nothing, first check that the soundbar is powered on and the volume is not at zero. Look for a light on the soundbar itself — if it is dark, the device is off. Press the power button and try again.

Next, go back into the TV's sound settings and confirm the soundbar is still selected as the output. Sometimes the TV reverts to internal speakers after a restart or software update. If the soundbar appears in the list but is grayed out or shows as unavailable, unplug both devices, wait 30 seconds, and plug them back in. This resets the connection.

If the soundbar still does not appear in the output list, the cable may be loose or faulty. Unplug the HDMI or optical cable from both ends, inspect the connectors for dust or damage, and plug it back in firmly. If you are using HDMI eARC, try a different HDMI cable — some cables do not support eARC even though they look identical to standard HDMI cables.

For Bluetooth connections, forget the pairing and start over. Go to the TV's Bluetooth settings, find the soundbar in the paired devices list, and select "Forget" or "Remove." Then put both devices into pairing mode again and reconnect. This clears any pairing errors that may have developed.

Choosing between eARC, optical, and Bluetooth

HDMI eARC is the best choice if both your TV and soundbar support it. It handles the most audio formats, including Dolby Atmos and DTS:X, and requires only one cable. Setup is automatic on most Samsung TVs, and there is no audio delay. The only downside is that you need an eARC-compatible soundbar, which is standard on newer models but not on older ones.

Digital optical cable is the reliable fallback. It works with almost every soundbar made in the last 15 years, costs very little, and has no compatibility issues. The trade-off is that it does not support advanced audio formats, so if your soundbar has Dolby Atmos, you will not hear it through optical. Optical is also slightly more prone to interference from nearby electronics, though this is rare in home setups.

Bluetooth is convenient for wireless listening but introduces a noticeable delay that makes it unsuitable for watching TV or movies. Use it only if you cannot run a cable and do not mind the timing mismatch. For everyday viewing, stick with wired connection.

Frequently Asked Questions

Do I need a special HDMI cable for eARC?

Standard HDMI cables work with eARC, but HDMI 2.1 cables are more reliable. If you already have an HDMI cable, try it first — most work fine. If the soundbar does not appear in your TV's audio output list, swap in a newer cable rated for HDMI 2.1 or higher.

Can I use both the TV speakers and soundbar at the same time?

Most Samsung TVs do not allow this. When you select the soundbar as the audio output, the TV speakers turn off automatically. If you want to hear from both, you would need to manually switch the audio output back and forth, which is impractical. Choose one or the other.

Why does my soundbar keep disconnecting from the TV?

For wired connections, a loose cable is the most common cause. Check that the HDMI or optical cable is fully inserted into both the TV and soundbar. For Bluetooth, move the soundbar closer to the TV or remove obstacles between them. If disconnections continue, forget the pairing and reconnect.

Will connecting a soundbar disable my TV's built-in speakers?

Not automatically. When you select the soundbar as the audio output, the TV disables its speakers. If you want to use the TV speakers again, go back to the sound settings and select "TV Speaker" or "Internal Speaker" as the output.

What if my soundbar has no eARC or optical port?

Use Bluetooth or check the soundbar's manual for other connection options. Some soundbars connect through a 3.5mm aux cable or RCA connectors, though these are less common on newer models. If your soundbar is very old, it may only support analog audio, which requires an adapter.
